[GEE TSE] can't display images from Landsat 4-9 collection

[Andreas Rabe]

Reported by @Philippe Rufin .

QGIS freezes when displaying a single image from the collection.

Note: when waiting for a long time, the image will appear.

Not sure why it takes so long. Further testing needed.

Found the problem!

This is the critical line inside the collection definition file (LANDSAT_COMBINED_C02_T1_L2.py):

collections = [l4, l5, l7, l8, l9]
collection = ee.ImageCollection(ee.FeatureCollection(collections).flatten())

After replacing it by a sequence of individual merges it works as expected again:

collections = [l4, l5, l7, l8, l9]
collection = ee.ImageCollection([])
for li in collections:
    collection = collection.merge(li)
